TALBOT C. DEXTER, OF PEARL RIVER, ASSIGNOR TO THE DEXTER FOLDER COMPANY,OF YORK, N. Y.

PAPER-REGISTERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 550,950, dated.December 10, 1895.

Application filed October 26, 1894.

To aZZ whom it may concern.-

Be it known that I, TALBOT C. DEXTER, of Pearl River, in the county ofRockland, in the State of New York, have invented new and usefulImprovements in Paper-Registering Machines, of which the following,taken in connection with the accompanying drawings, is a full, clear,and exact description.

This invention relates more particularly to the electrically-controlledpaper -registering machine shown in my prior application for patent,Serial No. 509,444, in which the gripper is caused to take hold of thepaper solely by mechanical force and caused to release the paper at theproper time by electric magnetic energy transmitted mechanically to thegripper. To effect this operation of the gripper, I found it necessaryto employ a lost motion in the mechanism which imparted reciprocatingmotion to the gripper in order to open the gripper for receiving themargin of the paper and subsequently close the gripper to take hold ofthe paper and draw it laterally. Said lost motion entails considerableWear of the joint by which the gripper is connected to the pitman.

My present invention is designed to obviate this defect and to increasethe efficiency of the registering-machine; and to that end the inventionconsists in the improved construction and combination of partshereinafter fully described, and specifically set forth In the annexeddrawings, Figure 1 is a plan view of my improved paper-registeringmachine applied to a paper-folding machine.

gage, which arrests the longitudinal movement of the paper preparatoryto being registered and folded. All of said parts are of the usualwell-known construction.

I do not limit my invention to its application to paper-foldingmachines, as it is equally useful on paper-feeding machines and othermachines requiring the paper to be fed to them one sheet at a time andsaid sheet to be adjusted to proper alignment preparatory to beingoperated on.

To the top of the frame A is rigidly secured a horizontal guide 0, whichis at right angles to the paper-supporting bars a a. Upon this guiderides the reciprocating slide D, from which extends rigidly the lowerjaw J of the paper-gripper. Said jaw is immediately beneath the panel ofthe paper. The upper jaw J of said gripper is hinged to the slide D atthe heel of the lower jaw, as shown at b, and is sustained normally inan open and raised position by any suitable means, preferably by aspring 0, connecting said jaw to an arm d,

which projects upward from the slide or heel of the lower jaw and hassecured to its upper end the electromagnet 'm, which extends rearwardfrom said arm. The upper jaw has rigidly affixed to it an arm d,extending upward from the pivoted end of the jaw andhaving secured toits upper end the armature 'm.

On'the slide D is carried an electric-circuit closerconsisting,essentially,of two yieldingly-supported poles held normallyin a cir- Quit-breaking position and in the path of the paper to beactuated to close the circuit by one of the poles coming in contact withthe edge of the paper. This circuit-closerI prefer to form of two smalllevers ll, pivoted at or near the center of their lengths to ears ee onthe under side of the slide D and projecting with their upper endsthrough slots in the jaws. The contact-point e onthe upper end of thelever Z is connected by a wire f to the magnet m, and wires f and fconnect, respectively, the lever Z and magnet with the battery L.

From the slide D depends a hanger h, terminating with a horizontal eyeor guide h, in which is supported one end of a push-bar g, which endabuts against the lower portion of the lever Z. Said bar is sustainedyieldingly ation of turning it.

as hereinafter explained. are adj ustable longitudinally on the push-barin a longitudinal direction and in its normal position by means ofcollars t' and t", attached to the bar 9 at opposite sides of thehanger, and an expansive springj, interposed between the rear collar 1"and hanger 72, which spring forces the bar rearward, which movement ofthe bar is arrested by the collar t coming in contact with the aforesaidhanger, as shown in Fig. 3 of the drawings. The lever l is made to restby gravity against the end of the push-bar 9, so as to maintain it incontact therewith. The outer end of the push-bar passes through an eye011 a bracket 7t, which is mounted on a guide '22 fixed to the frame Aparallel with the bar 9. provided with an arm 7c, in which is j0urnaleda screw 0, parallel with the guide it and passing through a nut securedto or formed in the side of the frame A. The screw is shouldered on thearm 7c", soas to cause the bracket to move longitudinally with thescrew. A hand-wheel o is attached to the outer end of the screw tofacilitate the oper- To the push-bar is attached a third collar t'between the bracket 7; and collar 1" and arranged in such a position asto come in contact with the bracket '7; during the latter part of theoutward or retrograde movement of the slide D. Said contact prevents thebar 9 from following the slide to the end of its said movement andthereby causing said bar to push the lever Z out of contact with thecompanion lever Z, All of said collars to permit the operation thereofto be regulated.

The slide D, which carries the gripper, receives its reciprocatingmotion from a rotary cam T by means of a lever 12, fulcrumed'on theframe A and having one end engaging thecam and the oppositeend'connectedto the slide D by pitman P.

In order to allow the gripper to be adjusted in its position sons tooperate on paper of different sizes, I make the pitman P adjustable inlength by forming the same of two end sections, which are screwthreaded, re-

spectively, right and left and coupled together by a turnbuckle orsleeve P, having corresponding right and left screw-threads in oppositeends. By turning said sleeve the two end sections of the pitman can bemoved either from or toward each other to increase or diminish thelength of the pitman,-as may be desired. The collars it 7 are to beadjusted correspondingly on the bar g.

The operation of the described registering maehine is as follows: Thepaper in process of being fed to the folding-machine is arrested in itsmovement by the end gage B. Then the slide D is pushed forward or towardthe paper, and in this movement the gripper is in its open position toreceive the margin of the paper between the jaws J Jand cause the edgeof the paper to push the lever Z into contact with the lever Z, andthereby close Said bracket is the electric circuit. This energizes themag net m, and by the attraction of the armature m the upper jaw J iscaused to press down upon the paper, which is thus gripped between thejaws. As soon as this is eifected the slide D receives retrogrademovement and causes the paper to be drawn along by the gripper until thecollar 11 011 the pushbar g strikes the eye of the bracket 70, wherebythe further movement of the push-bar is arrested. to move suflicientlyrearward to cause the push-bar to tilt the lever l, and thereby breakthe circuit. This allows the spring 0 to lift the upper jaw J, andthereby release the paper to be carried to the foldingrollers R R. Thegripper remains in its open position during the next forward movement toreceive the nextshe'et of paper in the manner before described.

Having described my invention, what I claim i's- 1. An electricallycontrolled paper registering machine comprising 'a reciprocating gripperhaving its jaws held normally in an open position, an electro'ma'gnetcausing by the attraction of its armature to close said jaws, a normallyopen electric circuit and a circuit closer in the path of the paper tobe actuated thereby as set forth.
